Development Of Uwb Antenna Array For Hyperthermia Treatment

An antipodal Vivaldi antenna is developed for hyperthermia treatment of brain tumor. The proposed antenna has overall size 82x94x1.6mm. The return loss parameter is less 10 dB starting from 0.1 GHz, range, when immersed in brain simulating liquid. The paper presents optimization of array structure to focus energy in the intended tumor location. Results indicate that the presented structure is promising in developing microwave imaging systems.
